Wellington, in the county of Lorain and State of Ohio, have invented acertain new and useful Im 'rovement in Combined Air eflectors, of whichthe fol- This invention relates to a combined air purifier and reflectoradapted to be applied to incandescent lamps, an

hasfor itso ject to prov de a vaporizlng 'devicefor convert.-

' ing various substances into a gaseous state for medicinal and otherpurposes, adapted to be mounted upon any standard size in candescentlamp bulb and to utilize the heat of said bulb to'vaporize or'volatilizethe substance contained therein. r

A further object is to provide a .device requiring no specialelectrical;connections and adapted to be mounted upon the lampfixtures'already in place.

A further object of the invention is to pro-- vide a simple,'efiicientand inexpensive device for disinfection and deodorization in a sickroom, in publicgatheringlplaces'or in the home.

The present invention also furnishes a reliable means for the treatmentand prevention of infections, respiratoryv diseases by the inhalation ofair, medicated by vapors from volatile oils and other suitablesubstances.

' This invention alsoprovides an excellent meansfor maintainin theproper humidity in the air, or for supp ying perfumes to the air intheatres, stores and homes.

A further objectof the invention is to provide a vaporizing devicewhichis easy to assemble,- cheap to manufacture, easy. to fill, cleanand re air.

v A further ob ect of the invention is to provide a vaporizing panadapted to be mounted upon any standard size incandescent bulb and toform a reflector therefor. A further object is to provide a vaporizindevice adapted to be mounted u on a stan 1 ard size incandescent lampbul regardless of the angle at which the bulb is mounted, and adapted tobe suspended on the bulb so that the contents will not spill.

A further object is to provide acne-piece va rizing pan which is made inone 1 ece rig requlres no screws or other attac g devices. A furtherobject is..to provide'a vaporizing device which is e-flicient in opera--ploy'ed. Referring to the accompangmg drawings cation, Fig. 1'

tion, cheap to manufacture andeasly clean and attach. Other'objects wi 1be apparent from the following description and accompanyling drawings.

The to owing description and accompanying drawings set forth in detailcertain neans embod ing the invention, the dis- .closed'means, owe'ver,constituting but one of the various mechanical forms in which theprinclple of the invention may be emfor1nin a part of this s'peci 1s asi e elevation of'the air urifying device mounted upon a lamp bulb,various positions of the lamp bulb being shown in dotted lines and aportion ofthe pan being broken away and shown in section; Fig 2 is a.perspective view of the device; and

is a side elevation showing the vaporizmg pan mounted upon an upwardlyprojecting bulb such asthe bulb of a pedestal lamp, the bulb being shownin dotted lines at an an le with respect to the vertical.

'ferring to the accom anying drawings, theair urifier consists'o avaporizing. pan

. formed in one iece from sheet metal to provide an annu ar trough 10 toreceive the fluid to be vaporized. The pain is provided with an outercylindrical wal tom 12, and an inner annular wall 13, the upper portion14'of whichQrcRects above the ugper' edge of the outer wa 11, and iscurve inwardly converging to a central circular top opening 15. I

The 0 ning 15 is of a diameter less than the maximum diameter of astandard incandescent lamp bulb, but of eater diameter than the neck ofthe bu b, so that the neck of the bulb may be inserted through the oening 15 from the bottom and screwed Fig. '1 of the drawing, the upperedge of the inner wall of thepan engaging-the bulb 1 16 between the neckportion thereofand the portion of maximum diameter. The inside of theinner wall 13 will be provided with .a reflecting surface so that thedevice serves as well as a va- 15 is of conas a reflector for the. lamporizer. Since the opemn as 11, a flat botsiderably greater diameter t nthe neckof the bulb to which it is attached, the. bulb may be disposedat various "angles witlr res'pect tothe vertical, as shownm dotted huesat 16" in Fig. 1.

may be disposed at various angles the vertical, as'shown in dotted linesin Fig. 3.

The trough 10 of the pan may contain a suitable liquid or solution forsupplying the desired ingredients to the atmosphere of the room in whichthe device is used. If it is desired to supply humidity to the air,water will be placed in the trough 10. For disinfection, itable fluidinsecticides or germicides may be employed. For medicinal treatments,suitable medicinal substances such as bal'sams, tinctures, volatileoils, etc., may be employed. For air purifying purposes, suitabledeodorants and disinfectants suitable for inhalation ma be employed.

An annular removable ller 17 of absorbent material may be placed withinthe trough 10 which is adapted to be saturated with the liquid which isto be vaporized. This filler is preferably of heat retaining materialand a non-organic substance which will not be chemically acted upon byliquids which are to be vaporized. Asbestos has been found to serve verywell for this purpose. This absorbent holder for the liquid serves toretain heat and causes the same to be more evenly distributedfacilitating the vaporization and preventing overheating of the liquidadjacent the heated wall of the pan. Substances such as some of thevolatile oils which are injuriously affected by light or excess heat areprotected against deterioration. Additionally the absorbent preventsspilling of liquid should the pan be accidentally tipped. In case thepan when used becomes tilted so that its bottom is somewhat inclined tothe horizontal the liquid will still be held by capillary attractionuniformly distributed throughout the filler.

Having described my invention, I claim:

1. A vaporizing pan comprising an annular trough having an outersubstantially circular wall and an inner wall concentric with the outerwall, said inner wall being rounded inwardly toward the top thereof toprovide at the openin an edge portion engageable with an incan escentlamp bulb whereby the pan may be supported at different angles withrespect to the axis of a bulb.

2. A vaporizing pan comprising an annular trough having an outersubstantially circular wall and an inner wall concentric with the outerwall, the major portion of the inner wall being of a diameter materiallygreater than the enlarged portion of an electric light bulb and taperinginwardly adjacent its upper edge to an opening of less diameter than atthe bottom whereby the upper edge portion of said wall forms asupporting seat engageable with a rounded portion of a lam bulb tosupport the pan therefrom at various angles with respect to the axis ofthe bulb.

3. A vaporizing pan comprising an annular trough having an outersubstantially circular wall and an inner wall concentric with the outerwall, said inner wall being rounded inwardly toward the top thereof toform a seat for engagement with an incandescent lamp bulb, the innerwall being adapted to be supported out from the bulb andthe innersurface of said inner wall having a reflecting surface.

4. A vaporizing pan having a layer of absorbent material on the bottomthereof.

A vaporizing pan having a porous layer of asbestos on the bottomthereof.

6. A vaporizing pan comprising an annular trough having the inner wallthereof formed to rest upon an incandescent lamp bulb and a removablefiller of absorbent material in the trough.

In testimony whereof, I hereunto ailix my signature.
